Guideline Overview Tool (GOT)

The main purpose of the Guideline Overview Tool (GOT) is to provide a compact overview that is easy to read and comprehend in order to support physicians in executing and analyzing therapies with clinical guidelines.

This overview has two main functions:

FishEye JTree

The Java Swing element "JTree" allows representation and navigation in tree structures. But as soon as the amount of hierarchical data structures increases (e.g. the file system) one can easily lose overview and orientation while navigating through different nodes on deep hierarchic levels.

InfoVis Tools - A Detailed Comparison of Information Visualization Tools Using a Reference Data Set

Many approaches to solve the problem of visualizing time-oriented data have been published in recent time, creating the need to categorize not only the methods to visualize time-oriented data but also the information visualization tools available on the market. Because of the difficulty of comparing such tools no agreement on a common categorization has been reached. This master's thesis uses a recently published categorization to perform a detailed comparison of several visualization tools, focusing on the temporal aspects of data.

CareVis - Interactive Visualization Methods to Support Protocol-Based Care

We provide multiple simultaneous views to cover different aspects of a complex underlying data structure of treatment plans and patient data. The tightly coupled views use visualization methods well-known to domain experts and are designed to facilitate users' tasks. CareVis enables a meaningful navigation, provides annotations on demand for not overwhelming the viewer, and helps to keep orientation by using focus+context techniques, thus increasing the flexibility in working with treatment plans and patient data.

Visualization Technique for Time-Oriented Data with Semantic Zoom

This project is part of the research project VisuExplore, which is dealing with the interactive visualization of patient data to assist physicians and medical staff.

Prototype:

The visualization techniques have been developed in the Midgaard project but so far only been implemented in Flash to demonstrate the idea of the concept.

HorizonVis – Interactive Visual Exploration of Multivariate Medical Measurements in Diabetes Care

Multivariate, time-oriented data plays a central role in many domains such as medicine, finance, or environmental engineering. Information Visualization can be an instrument to make such vast datasets intuitively comprehensible. As the number of time series increases, visualizations need to be space-efficient. Horizon graphs [Reijner, 2008] are an innovative approach to reduce required space by dividing the a chart into bands and layering these.

TimeRider – Visualizing Patient Cohorts by Animated Scatter Plots

The aim of this project was to develop a program, which helps to show the development of medical parameters over time. These (30) parameters result from examinations of patients who are treated for diabetes. The examinations take place in irregular intervals from six weeks up to three months.

EviGuiDe –  Embedding the Evidence Information in Computer-Supported Guidelines into the Decision-Making Process

In this project we propose a methodology that supports guideline users during the decision-making process on the basis of a semi-formal representation of the evidence information that can be found in Clinical Practice Guidelines (CPGs). A semi-formal representation is required to handle evidence information in computer-interpretable guideline representation languages. For this purpose, we have developed a meta schema that covers various kinds of grading systems including graded and ungraded evidence informaton.

PDF2Table – Utilizing Table Patterns

If we surf the web we can find PDF files in heaps. Once technical details of an amazing five mega pixel digital camera, once a statistic about the last two years incomes of an enterprise, and once a brilliant crime novel of Sir Arthur Conan Doyle is saved in a PDF file. The widespread use of this file format takes the focus on the question of how to reuse the data in such a file. Many things are already done in this area. For example, there are several tools that convert PDF-files to other formats.

NegHunter – Negation Detection in Medical Documents Using Syntactical Methods

NegHunter is a program to detect negated concepts in medical documents using syntactical methods.

LASSIE – modeLing treAtment proceSSes using Information Extraction

Modeling clinical guidelines and protocols in a computer-interpretable format is a challenging, but burdensome and time-consuming task. Existing methods and tools to support this task demand detailed medical knowledge, knowledge about the formal representations, and a manual modeling. Furthermore, formalized guideline documents mostly fall far short in terms of readability and understandability for the human domain modeler.

iUMLS – A Program to Enlarge and Modify Output of MetaMap

iUMLS provides an API to enhance, modify, and serialize the output of the MMTx program.

EviX – Facilitating Evidence-based Decision Support Using Information Extraction and Clinical Guidelines

The goal of the proposed project is the experimental application and further development of promising approaches in the area of semi-automatic creation of computer-interpretable clinical guidelines and the execution of evidence-based recommendations. We expect contributions to ease the creation of computer-interpretable guidelines and support of the medical staff in their daily routine and decision-making.

DeTable – A Wrapper for Complex HTML Tables

The main purpose of this student project is a wrapper that transforms complex HTML tables into an XML format. The complexity of the HTML tables is defined by the occurrence of spanned cells.

CPGPro – Extracting Process Information from Clinical Practice Guidelines

Like in many other domains, computerization is seen as a means to facilitate the effective use of Clinical Practice Gudelines (CPGs). Therefore, transforming CPGs in a machine-readable and executable format has been the gist of research. Consequently, many guideline representation languages are developed and modelling tools are designed which convert CPGs in their corresponding models defined in these guideline representation languages. Available modelling tools are restricted in the way that they only allow a manual computerization process.

VisuExplore – Gaining New Medical Insights from Visual Exploration

VisuExploreThe application of modern technology in clinical practice leads to a massive increase in quantity and complexity of electronically acquired medical data and information. Current commercial clinical information systems are faced with the explosion of available medical data and users of these systems ask for alternative, more intuitive solutions.

MobiGuide: Guiding Patients Anytime Everywhere

MobiGuide LogoMobiGuide (MG) will develop a patient guidance system that integrates hospital and monitoring data into a Personal Health Record (PHR) accessible by patients and care providers and provide personalized secure clinical-guideline-based guidance also outside clinical environments. MG's ubiquity will be achieved by having a Decision Support System (DSS) at the back end, and on the front end by utilizing Body Area Network (BAN) technology and developing a coordinated light-weight DSS that can operate independently. Personalization will be achieved by considering patient preferences and context. Retrospective data analysis will be used to assess compliance and to indicate care pathways shown to be beneficial for certain patient context.

ViENA: Visual Enterprise Network Analytics

ViENA Visual Enterprise Network AnalyticsThe research project VIENA (Visual Enterprise Network Analytics) aims to develop and test a prototype software of visual network analysis that will be capable to support organizational consulting services. As its focus will be the visualization of change, its main purpose is the display and evaluation of change management processes.

MapFace - A Graphical Editor for MetaMap Transfer (MMTx)

MapFaceThe MMTx program [1] tokenizes free text of medical documents into phrases and maps UMLS concepts [3] to the medical concepts identified within these phrases. Due to the complexity of this task, it is still necessary to correct parts of the tokenization as well as the mapping of UMLS concepts.

HypoVis: Modeling Hypotheses with Visual Analytics Methods

The primary goal of Visual Analytics is the close intertwinedness of human reasoning and automated methods. Our goal in HypoVis is the design and development of a Visual Analytics process that uses the inherent structure contained in time-oriented data as a way to improve the integration of human reasoning. This structure can, for example, be seen in the calendar aspect of time being composed of smaller granularities, like years and seasons. Our focus is the generation of models from hypotheses, consisting of bringing the hypotheses into an automated system, and validating it.

EXPAND: EXploratory Visualization of PAtent Network Dynamics

The distributed nature of modern research and development has lead to a highly differentiated knowledge and technology landscape, which forms the complex and continuously evolving environment for individual and organizational actors in the economy, science, and technology realm. Public patent databases, which are regulating these developments by ongoing accumulation of semi-structured patent documents, are a rich source of information that has not been sufficiently leveraged for synoptic science and business analytical tasks yet.

VisMaster CA -- Visual Analytics - Mastering the Information Age
